I thought it was going to be a 500 gallon it just grew 100 gallons. Even with a 500 or 600 I wouldn't get the id there very active swimmers and need a lot of room to swim you gonna need more like a pond for one of these.
I don't think so man, as they said, they like to school. and if they aren't they will probably feel un-secure, making them skittish, and that will make for a huge busted tank.
